I can't figure out why, but before my form is even displayed, the CheckChanged event fires. I don't even have a chance to check anything. Has anyone seen anything like this?
View 3 RepliesHow do I create a new event in a base page class that fires after all derived pages have fired their load events but before any controls fire their load events.
The following code fires the event before the derived page's load event. I want it to fire the event after the derived page's load event but before all control load events:
Base Class:
Public Event FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs)
Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
RaiseEvent FirstLoad(sender, e)
End If
End Sub
Derived Class:
Private Sub Page_FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.FirstLoad
'Stuff here happens before controls load but only on first page loads'
End Sub
In my web form, i have 2 drop downlist controls. eg. dropdown1 and dropdown2. I will change the dropdownlist1 item, consequently selectedindexchanged event fires and reloads the dropdownlist2 items. And i have another button also in order to get the result based on the dropdown1 and dropdown2. Lets say for example, i have a list of countries in dropdown1 and a list of states in dropdown2. I selected "India" in dropdown1 and correspondingly "Tamilnadu" in dropdown2. And then click a button which calls the dataset based on dropdown1 and dropdown2. The problem i face here is, whenever i click on the button to load the dataset, dropdown1 value remains the same as the dataset is not called again, whereas the dropdown2 value changes to the first one as it gets called automatically during postback. For your information, I have loaded both the lists in the page load using (!IsPostback) property.
My coding is as follows:
protected void Page_Load(object sender, EventArgs e)
{
try
{
if (Session["sesUserName"] == null)
{
Response.Redirect("sessionExpr.aspx", false);
}
else
{
lblStatus.Visible = false;
pnlEvaluate.Visible = false;
if (!IsPostBack)
{
fnLoadDropDown1();
fnLoadDropdown2();
}
}
}
catch (Exception ex)
{
throw ex;
}
}
public void fnLoadDropDown1()
{
dsLoadDD1 = objWebRef.fnLoadOnlineTest();
if (dsLoadDD1.Tables[0].Rows.Count > 0)
{
ddTestTitle.DataTextField = "vchTestTitle";
ddTestTitle.DataValueField = "intTestID";
ddTestTitle.DataSource = dsLoadDD1.Tables[0];
ddTestTitle.DataBind();
}
}
public void fnLoadDropDown2()
{
dsLoadDD2 = objWebRef.fnLoadOnlineTest();
if (dsLoadDD2.Tables[0].Rows.Count > 0)
{
ddUser.DataTextField = "vchUser";
ddUser.DataValueField = "intUserID";
ddUser.DataSource = dsLoadDD2.Tables[0];
ddUser.DataBind();
}
}

i'm creating and adding checkbox in my code behind to a parent control.
autopost back is true, it's posting back on being checked, but i'm not sure how to capture the fact that it's checked before I recreate/add it to the parent control again.
i can search all controls and find it prior to re adding it to the parent, but it never shows checked...

I have a script manager and 3 update panels on my page. I am not very familiar with AJAX but I would think anything in the contentTemplate would not cause a postback and page reload, but they all do, here is the outline of the SM and UpPanels

<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="sm" runat="server" />

View 3 RepliesI am using a third party gateway. The third party gateway does not support query-string , so i will need to post the form to pass the values to the given URL and another thing is that they don't expose the web-services so we need to use their page and that means we need to host it in an iframe in asp.net
so what i did is that i have hidden fields that will be used as parameters as depicted below
Code:
<input type="hidden" name="p1" value='4635' />
<input type="hidden" name="p2" value='Reference_test' />
<input type="hidden" name="p3" value='Purchase credits' />
[Code]..
Now the purpose of this , is to load the iframe after the page load event of the asp.net gets fired.
Now my problem here is that when the iframe loads , it does not pass the parameters to the url that is being set in the iframe.
I have attached the example, project. (2kb)
When you run the project you will notice when the iframe loads there is an Error
"NO VCS ID"
now this means that the parameters were not passed when the Iframe loads , i can understand because it seems like iframe does not do a full form post. so to demonstrate what i want, click the proceed button and you will notice it will give you a page with no errors and it will be a page where credit card details are required , i want to iframe to load that the first time.
now a days i'm working on my project. In project there is a aspx page which is binded with a masterpage, the problem is that when i run the project in debugging mode i found that page load event of a page is firing two times instead of one along with masterpage page's page load event. This is crreating a problem in filling a grid. I searched through the internet for this problem some says that it may happen if u have any image whose src="" or due to some bad HTML's on page .But i've gone through the page it does not contain any image whose src="" .

I have a user control that will basically be a header in most of my pages, but not all. I want some code in the user control to be run before the page load event of the page that holds the user control, but the page load event fires before the events in my user control. Is there a way around this?
View 3 RepliesUsually when we create an aspx page and then open the aspx.cs page we can see a protected void page_load().So my question is why that should be protected in default.Can we give other access modifiers.
